The FX12-Knock is analog amplifier for vibration sensors. It will amplify small signals from piezo and other low level sensors for reading by a 0-10V input.

If
you use the analog output version, it can be run to a FX350 or other FX controller and drive all
the logic you’d need. The SSR (solid state relay) version could open a
maglock when a certain pressure is reached, but no further logic, latching,
etc.
